A fast scan axis for a high speed flat bed scanner has an elongated reciprocating table for securing the material to be scanned. The table is narrower than the material and portions of the material overhang the table. The overhanging portions are supported by stationary support surfaces with a plurality of air ports in the surface thereof for providing an air bearing support for the overhanging portions. The moving mass of the scanner is thus kept small enabling fast scanning of the material.
